SHARPENER FOR SHEARS ANDSOISSORS.

Specification of Letters Patent.

Application filed August 28, 1908.

Patented July 6, 19094 Serial No. 450,669.

To all whom it may concern.

Be it known that I, MILO E. INGRAM, a citizen of the United States of America, residing at Butler, in the county of Butler and State of Pennsylvania, have invented certain new and useful Improvements in Sharpeners for Shears and Scissors, of which the following is a specification, reference being had therein to the accom anying drawing.

This invention re ates to sharpeners for shears and scissors, and the object of my invention is to provide a simple and inexpensive device for sharpening the blade of a pair of shears or scissors and maintain the proper bevel or cutting edge upon the blade.

Another object of my invention is to provide a sharpening device having an adjustable file or sharpening medium that can be moved from time to time as the same becomes worn.

A further object of the invention is to provide a portable sharpening device that can be supported at the proper inclination for conveniently sharpening the blades of a pair of shears or scissors.

Vith the above and other objects in View, which will more readily appear as the invention is better understood, the same consists in the novel construction, combination and arrangement of parts to be presently described and claimed.

In the drawings, Figure 1 is a front elevation of the sharpening device, Fig. 2 is a rear elevation of the same, Fig. 3 is an end elevation of the device, Fig. 4 is a plan of a file or corrugated piece of metal, Fig. 5 is a cross sectional view of the sharpening device, and Fig. 6 is a plan of the same.

In the accompanying drawings 1 designates an oblong block of a hard and durable wood. This block in cross section conforms in shape to a parallelogram, the inclined side 2 constituting the front of the block and the inclined side 3 of the rear block, whereby when the sharpener is used and rests upon a suitable support, the block will be inclined away from the person sharpening the blades of a air of shears or scissors. The front side 2 of the block is provided with a diagonally disposed slot 4, this slot extending from the lower left hand corner of the block to the upper right hand corner thereof and corresponding in depth to approximately three quarters of the width of the block. In cross section, this slot is at right angles to the front side 2 of the block, whereby a fiat file or roughened strip of metal 5 arranged in the slotwill be held at right angles, relative to the base or support of the block 1. The top of the block is rovided with a transverse slot 6 communicating with the slot 4, whereby a portion of the file 5 corresponding in width to the slot 6 will be exposed.

To retain and adjustably hold the file 5 within the slot 4, the front inclined side 2 of the block 1 is provided with a set screw 7 having a disk 8 for frictionally en aging the outer longitudinal ed e of the file 5 and firmly holding said file within the block, while a shear or scissor blade 9 is drawn over the file 5. The inclination of the file 5 within the block 1 preserves the roper bevel upon the cutting edge of the b ade 9, when the same is drawn over the file 5. Should the blade 9 be placed in engagement with .the upper exposed edge of the file 5 and drawn across said file, the blade immediately travels to the lower ex osed edge of the file, as shown in Fig. 1 of tfie drawings, whereby the lower side of the slots 6 will serve functionally as a guide for the blade 9 while the same is drawn over the file. It will thus be observed that a very small surface of the file 5 is actually worn when sharpening the blade 9, consequently the use of the file is considerable on account of its length, and can be easily adjusted to present new filing surfaces, when one surface has become worn.

It is obvious that various materials can be used in the construction of my sharpener without departing from the scope of my invention.

Having now described my invention what I claim as new is A shear and scissor sharpener comprising an oblong block inclining in one direction and having one side provided with a longitudinally-extending diagonally-disposed slot, said slot downwardly inclined in transverse section and said slot extending substantially from one upper corner to the opposite lower greater width than said diagonally disposed 10 corner of the block, an adjustab e file mounted in said slot, a disk extending across said slot for retaining a file in its adjusted position, and a screw extending through said disk for securing the disk in position, and said block having a transverse slot formed in the top thereof, said transverse slot of a depth as to expose a portion of said file and of a slot. o In testimony whereof I aflix my signature in the presence of two witnesses.

MILO E. INGRAM.
